High electrostatic fields of cations in zeolites and other catalysts is shown to modify the elctronic level struture of molecules. As an example, nitrogen molecules become nitrogen oxide like. It is argued that this is relevant for the Haber–Bosch synthesis. It is also pointed out that fields of the order of volts per Angstrom are equivalent to pressures of GigaPascals.

催化中的场致化学：高压和高场

沸石和其他催化剂中阳离子的高静电场显示出可以改变分子的电子能级结构。例如，氮分子变为氮氧化物。有人认为这与Haber-Bosch综合有关。还要指出的是，每埃伏特量级的磁场等于千兆帕斯卡的压力。
